本次由於需要搭建一套環境，但是所需硬件配置不足，需要進行統計采購。那么就需要得知服務器現有配置，所以這次會介紹些常用的命令和工具來查詢硬件信息。其實也可以通過像DELL廠商的IDRAC控制台來獲取這些信息，但是比較尷尬的是IBM在獲取硬盤信息方面支持比較差，僅顯示物理磁盤數量，能夠獲取的信息很少，這時就需要像storcli這種專業工具來收集。本章使用的命令查詢需求比較單一，后續會在實際使用中慢慢補充上來。
一、查看服務器對應 IPMI 地址
[root@node-1 ~]# ipmitool lan print

二、查看網卡速率
[root@node-1 ~]# lspci | grep Ethernet #列出每個pci總線上的設備，通過grep過濾可得到網卡設備列表，這里看到總計8個網卡
06:00.0 Ethernet controller: Intel Corporation I350 Gigabit Network Connection (rev 01)

20:00.1 Ethernet controller: Broadcom Limited NetXtreme II BCM57810 10 Gigabit Ethernet (rev 10)
[root@node-1 ~]# ethtool eth0 #查看單塊網卡的詳細信息

三、查看內存信息
[root@node-1 ~]# cat /proc/meminfo
[root@node-1 ~]# dmidecode -t memory #此命令會列出每條內存的型號、頻率等詳細信息
Handle 0x000A, DMI type 17, 34 bytes

四、使用 storcli 查看服務器硬件基礎信息
[root@node-1 ~]# rpm -ivh storcli-1.18.05-1.noarch.rpm #安裝包請見文章末尾
[root@node-1 ~]# /opt/MegaRAID/storcli/storcli64 show all #查詢所有信息並show，在system overview下看到controller（縮寫ctl）列數字就是controller號，得知node-1這台機器的controller號是0
System Overview :

[root@node-1 ~]# /opt/MegaRAID/storcli/storcli64 /c0 show #顯示contrller0的raid卡的版本、功能、狀態、以及raid卡下的物理磁、邏輯盤信息，這里我需要看物理磁盤的容量情況，可以在PD LIST部分找到
如果不需要其他信息，和我一樣只需要知道物理磁盤信息的話可以使用如下命令
[root@node-1 ~]# /opt/MegaRAID/storcli/storcli64 /c0/eall/sall show
Controller = 0
Status = Success
Description = Show Drive Information Succeeded.

-------------------------------------------------------------------------
五、不想安裝 storcli 的情況下查看硬盤型號信息
[root@node-1 ~]# cat /proc/scsi/scsi|grep 'Model:' #node-1 是 IBM X3650 M4
Vendor: IBM Model: ServeRAID M5110e Rev: 3.34
Vendor: IBM Model: ServeRAID M5110e Rev: 3.34
Vendor: IBM Model: ServeRAID M5110e Rev: 3.34
Vendor: IBM Model: ServeRAID M5110e Rev: 3.34
Vendor: IBM Model: ServeRAID M5110e Rev: 3.34
Vendor: IBM SATA Model: DEVICE 81Y3682 Rev: D001
[root@node-5 ~]# cat /proc/scsi/scsi|grep 'Model:' #node-5 是 DELL R720，ST1000NM0023就是硬盤的型號
Vendor: SEAGATE Model: ST1000NM0023 Rev: GS0D
Vendor: SEAGATE Model: ST1000NM0023 Rev: GS0D
Vendor: SEAGATE Model: ST1000NM0023 Rev: GS0F
Vendor: SEAGATE Model: ST1000NM0023 Rev: GS0D
這種方式在硬盤做 raid 后不便於查看，例如下面查看我另一台服務器所看到到的，顯示只有一塊磁盤設備
[root@node-1 ~]# cat /proc/scsi/scsi|grep 'Model:'
Vendor: DELL Model: PERC H710 Rev: 3.13
Vendor: TSSTcorp Model: DVD-ROM SN-108FB Rev: D150
接下來通過 lsblk 查看設備情況，發現這塊盤總容量2.7T（我這里使用的盤是1T的SAS盤，可以倒推出是4塊1T盤組成的raid5）正好對應上我在IDRAC界面中看到的四塊物理磁盤
[root@node-1 ~]# lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 2.7T 0 disk
├─sda1 8:1 0 24M 0 part
├─sda2 8:2 0 200M 0 part
├─sda3 8:3 0 250M 0 part /boot
├─sda4 8:4 0 1.4T 0 part
│ ├─os-root 253:0 0 1.4T 0 lvm /
│ └─os-swap 253:1 0 32G 0 lvm [SWAP]
└─sda5 8:5 0 1.3T 0 part
└─mongo-mongodb 253:2 0 1.3T 0 lvm /var/lib/mongo
sr0 11:0 1 1024M 0 rom
storcli安裝包各平台百度網盤鏈接地址（可在官網下載 https://www.broadcom.com/site-search?q=storcli）

續：在檢查過程中發現IBM服務器上有兩塊disk告警，聯系維保需要提供FRU號，但是人又不在現場沒辦法拔盤拍照。所以需要通過storcli來查詢盤對應FRU號。
六、查詢硬盤FRU號
[root@node-2 ~]# /opt/MegaRAID/storcli/storcli64 -PDList -aAll | grep FRU #如果想查看具體信息可以去掉過濾條件
IBM FRU/CRU: 42D0638
IBM FRU/CRU: 49Y2023
IBM FRU/CRU: 49Y2004
IBM FRU/CRU: 49Y2023
IBM FRU/CRU: 49Y2004
IBM FRU/CRU: 49Y2023
從上可以看到有兩對重復的FRU號，懷疑可能是組成raid，那么就要通過storcli查看下硬盤raid情況
(1)查看邏輯磁盤
[root@node-2 ~]# /opt/MegaRAID/storcli/storcli64 /c0/vall show #這里看到有5塊邏輯磁盤，通過 /c0 show 命令查看物理磁盤發現有6塊，繼續向下查看硬盤 raid 情況。
Controller = 0
Status = Success
Description = None

(2)查看邏輯磁盤大小、raid結構
[root@node-2 ~]# /opt/MegaRAID/storcli/storcli64 /c0/v0 show #可以看到 TYPE 為 RAID1，兩塊 600G 盤做的 RAID1，正好能夠對上6塊物理磁盤
Controller = 0
Status = Success

[root@node-2 ~]# /opt/MegaRAID/storcli/storcli64 /c0/v1 show #可以看到 TYPE 為 RAID0

依次查看 /c0/v0……4，結果為 v0 raid1 其余四個邏輯磁盤均為 raid0
